Plazit Polygal introduces the next generation of polycarbonate sheets:
Polygal Topgal, the standing-seam panel system.
Backed by 35 years of experience that began with the world’s first multi wall polycarbonate sheet, the Polygal Topgal panels and components integrate the unique properties of the multi wall structure to produce superior rigidity and thermal insulation that ensure maximum strength and complete sealing. Manufactured in 600mm and 1000mm widths (center to center) and in thicknesses from 8mm to 20mm.
Available in standard colors as well as special color layers that selectively reflect solar radiation.
Topgal panels feature a UV protective layer to protect against yellowing, and are covered by a 10 Year Warranty against breakage and yellowing.

· LT - Light Transmission in % according to ASTM D-1003, measured between ribs.
· SHGC - Solar Heat Gain Coefficient measures how much heat from the sun is blocked. It takes into account all conduction, convection and radiation effects involved. The lower the SHGC, the more a product is blocking solar heat gain. Blocking solar heat gailn is particulary important during the summer in hot climates.
